Question

A correlation of r = -.60 means what percentage of the variability in one score can be accounted for by its relationship with the other score?

1) 36%
2) 64%
3) 40%
4) 60%

Answer 1

The coefficient of determination, represented by r², is the square of the correlation coefficient. In this case, the correlation coefficient is -0.60, so the coefficient of determination is 0.36 or 36%.

Step-by-step explanation:

The coefficient of determination, represented by r², is the square of the correlation coefficient. In this case, the correlation coefficient is -0.60, so the coefficient of determination is (-0.60)² = 0.36. When expressed as a percentage, 0.36 is equal to 36%. Therefore, 36% of the variability in one score can be accounted for by its relationship with the other score.
